transducer heating for reliable use even in cold conditions

Transducer heating for use in cold conditions

Transducer heating for reliable use in cold conditions

To prevent icing of the front surface and for reliable measurement even at temperatures close to and below freezing, we equip our ultrasonic transducers with an optional transducer heating. The heating element prevents the transducer from freezing and the build-up of frost, snow and ice. For many of our customers in the anemometry sector, the installation of a heater is now standard equipment.

Reliable wind measurement under extreme conditions

Measuring devices on wind turbines are often exposed to extreme environmental conditions, especially in mountainous regions or offshore wind farms. These areas are subject to high wind speeds, heavy precipitation, snowfall, and freezing temperatures. Such conditions can significantly impair the functionality of sensitive components such as ultrasonic transducers.

Our integrated heating solution reliably protects the transducer from frost and moisture. It prevents critical parts from freezing and ensures that measurements remain accurate even at sub-zero temperatures. Even in the most adverse weather conditions—from storms to snowfall—the heating system enables continuous and reliable wind measurement. For operators, this means less downtime, greater safety, and maximum efficiency in energy production.

Heating technology in practical testing: Snowfall shows the difference

In the following test on November 29, 2023, an identical SC031 transducer without heating (left) and with heating (right) were each placed in an anemometer on an outdoor test bench and electrically contacted. Even after the first snowfall, a clear difference in the surface properties of the two samples can be seen. While the snow is deposited in the area without heating, it thaws directly on the transducer with heating. It can also be seen that the heater not only heats the transducer, but also a larger area around it.

Outdoor test proves: heating function ensures reliable performance

Over the course of a week and after further snowfall at constant temperatures between -9°C and 0°C, the difference between the two samples becomes even clearer. While the transducer without heating is covered by a layer of snow several centimeters thick, the transducer with heating has a larger area melted free of snow. This allows for continued reliable measurement and the above-mentioned reliable protection against icing and covering of the front surface.
